| Abstract: | Lightweight design is one of the key points of mission system design for special aircraft. Based on the analysis of the structure and stress of the ATR cabinet mounting frame in the cabinet,this paper introduces a lightweight structural design scheme of the ATR cabinet mounting frame in the cabinet. The finite element method is used to simulate the modal and random vibration. The obtained modal vibration mode and the stress and deformation under the random vibration condition are analyzed, and the remarkable effect of weight reduction is achieved. Further, the engineering practice is also presented. The technical points in the application are explained, which can be referred by the peers. |
